Operating Instructions
The DieHard 71341 features intelligent, microprocessor-controlled charging for optimal battery health.
Connecting to a Battery:
- Ensure the charger is unplugged from the AC outlet.
- Connect the red positive (+) clamp to the positive (+) battery terminal.
- Connect the black negative (-) clamp to the negative (-) battery terminal. For vehicles, connect the negative clamp to the vehicle chassis away from the battery and fuel line if the battery is still in the vehicle.
- Plug the charger's AC cord into a standard 120V AC outlet.
Selecting a Mode:
The charger automatically senses 6V or 12V battery voltage. Use the "Rate Selection" switch on the control panel to choose your desired operation:
- Charge/Maintain (6A/2A): For standard charging and long-term battery maintenance. The multi-stage charging process prevents overcharging and switches to maintenance mode when fully charged.
- Boost (50A): Provides a quick energy boost to a discharged battery.
- Engine Start (250A): Delivers maximum power to jump start your vehicle. Follow vehicle manufacturer's instructions for jump starting.
